Is anyone shooting the .416-.338? I've found the drawings of the case dimensions for the 416-338 and the 416 Taylor. The two cartridges appear to be nearly identical except the 416-338 has a longer neck. Does anyone have any loading data? How does it compare to the 416 Taylor? Any info is appreciated.

To the best of my knowledge, the .416 tailor was developed by necking-down the .458 Winchester Magnum cartridge to .416 diameter. The same principle applies to the .338 Winchester, 7mm Remington and .264 Winchester Magnum cases.

You could make .416 brass by necking up .338 Win Mag brass to .35 caliber, then to .375, and finally to .416, or you can neck-down .458 Win Mag brass. :wink:

Arizona Jake, the 416 taylor and the 416-338 are two similar, but different cartridges. I was looking for 416 cartridges on the 'reloadbench' site and I found both the 416 taylor and the 416-338. The main difference between the two is the 416 taylor has a .346" long neck and a case length of 2.500". The 416-338 has a .426"long neck and a case length of 2.525". I've read a few articles on the 416 taylor, but I've never heard of the 416-338, I was wondering if anyone could give me more information about it.

JK, I have to admit that my knowlege isn't anymore than yours. I found one load for the Taylor, 71 grs. IMR4320. I suspect the Taylor to have about a 1gr + advantage over the 338 with it's sharper shoulder and shorter neck. Who and when it was developed( 416-338), I haven't a clue.
I think, (swag) the Taylor required modification for feeding( ramp and follower), the 416-388 came about to eliminate this situation. Which could be done with a simple rebarrel job on standard length mag action.
I know this don't help you alot,,,sorry :oops:

onesonek, I have a 98 mauser with a pitted barrel that I plan on using. A cartridge with an aol of 2.900" will fit into the magazine. I think the only modifications that need to be made, besides the rebarrel, are to the bolt face and the magazine follower. I agree with you, that there would be little difference in the case capacity. I like to shoot cast bullets, so I like a case with a longer neck, which is why I was wondering about the 416-338. But I think the 416 taylor would do just fine. I have a few loads for the 416 taylor, but nothing on the 416-338. I think I could down the 416 taylor loads a few grains for the 416-338 and be ok. I was just wonder if any readers of this forum had hands on experience with the 416-338.

Joe Kool,

Hope this might assist. I came across an article by RF Chatfield-Taylor on the 416 Taylor (Guns & Ammo April 1973 page72) on the 416 Taylor. These are Mr Chatfiel-Taylor's loads 65 grs of IMR4064 for a 400gr sodid and soft point projectiles for a velocity 2,250 fps and ME of 4,500 ft-lbs. These were fore through a Winchester African in 416 Taylor. Of, course you use these loads at your own risk as I accept no responsibility for them.

Joe Kool,

Correction. That was 64 Grs of IMR 3031 NOT 65Grs of IMR 4064.

magnum308, thanks for the info. I've been doing some research on 411 and 416 cartridges. The 411 Hawk looks like a good cartridge. There is a 416 based on an improved 376 Steyr case. I found an article on the 400 Whelen, a similar cartridge to the 411 hawk but with a longer neck. The article had a drawing of the chamber dimensions. The chamber's shoulder diameter is .458", and the neck diameter is .435"-.440". I may be able to up the bullet to .416". If I make the cases from 30-06 clyinder brass, the neck diameter, with a 416" bullet seated, should be 441". With a case shoulder diameter of .455" or .456", there should be enough shoulder to head space on. The article said the 400 Whelen worked fine, if the chamber and the loading dies were the correct dimensions. But uping the bullet diameter to .416" may be too much. I've designed a few wildcats but never one with such a small shoulder. I need to make a few phones to people that can help me, to see if it's possible

I have built several .416 Taylors for customers and you can make your brass from either .458 Win cases or .338 brass, however it is easier to neck down then neck up. Performance wise the Taylor is very close to the .416 Rigby but operates at higher pressures to achieve this level of performance. It is a great cartridge and will work fine on all game form deer to the really big stuff, even those that might eat you. They loose their appetite real quickly when smacked with a 400 grainer at 2250 to 2300 feet per second.

Judson, Thanks for the info. Sorry for the delay in getting back to you, business has been too good, I have not had time to get here to Graybeards forums. I read articles of the effectiveness of the 416 calibers. I've been wanting to build some 416 cartridge, not sure which one. I like the 416 Taylor. I like to shoot cast bullets, so the longer neck of the 416-338 looks good. Still doing research. Z-Hat has a 416 on a improved 376 Steyr case, that looks interesting.

For what it is worth, I should have my 416 Taylor up and running by late August. VZ-24 action with a #5 Douglas barrel in a laminated stock with crossbolts. It is drilled for a Williams FP peep, and scope mounts. It will have a 2 1/2x Leupold on top. CAN'T WAIT.

I figure the 458WM brass should be around for a LONG time, and Lee has 416 Taylor dies for $23 and change. Not to mention I got 200 pieces of 458 brass from a fellow for just the cost of shipping, so 416 Taylor it was.
